The race for next-generation aircraft engines is intensifying as Airbus and CFM International promote the open-fan concept as a breakthrough for fuel efficiency and lower emissions. However, alongside the bold vision, CFM is also studying a more conventional engine backup, highlighting the industry’s cautious approach toward future propulsion technologies.
Open-fan promise:
The advanced engine design is expected to deliver significant fuel-burn reductions and support mid-2030s clean-sheet aircraft programmes.
Industry backing:
Major aerospace players, including Boeing, are closely tracking the technology for next-generation single-aisle jets.
Efficiency & sustainability goals:
The concept is being positioned as a key solution to cut operating costs and reduce carbon emissions.
Challenges beyond technology:
Integration with airframes, airport infrastructure, certification norms, and maintenance requirements remain critical hurdles.
CFM’s dual strategy:
While publicly championing open-fan engines, the manufacturer is quietly evaluating a more traditional advanced engine as a fallback option.
Risk management move:
The parallel study ensures readiness if the radical design faces delays or operational constraints.
Mid-2030s timeline:
The outcome will play a decisive role in shaping the propulsion choice for future narrow-body aircraft.
